Be it known that I, JOHN 'J. E mzlnu, a citizen of the United States, residing at Rushville, in the county of Bush and State of Indiana, have invented-a new and useful Cultivator, of which the following is a specification.

My dDVQDtIODIQlZLiJS to improvements :in

culti-vators and'one of the objects of the invention is tojprovide a cultivator for corn which will readily travel between the. rows of corn properly manipulating the ground and which will be substantially selfaguiding and which will ,provide a means to .permit theoperator to ride thereon instead, as has heretofore beenthe custom, follow the same on foot.

Anotherzobjectpf my invention is to ,pro-' vide a-cultivatorwh1ch, while possessing theabove mentioned advantages, will a'lso turn the down corn which may have been knocked or blown across the row and replace the corn in its normal position so that the corn stalks and the like will not be cut by.

the cultivator.

For the purpose of disclosing my '1I1V8I1- tion I have illustrated one embodiment thereof in the accompanying drawing in which Fig. 1 is a plan view of a cultivator embodying my invention;

Fig. 2 is a longitudinal sectional view, and Fig. 3 is a detail view of means for securing the front ends of the cultivator frame at 5 and is secured to a front supporting plate 6. This plate has an upwardly extending arcuate flange 7 which is slotted asat 8 to receive the retaining bolts'9 extending through the curved ends 5 of theside members. The supporting plate 6 hassecured thereon a vertically extending socket 10 which receives: one end of a spindle the lower end of Which is adapted to extend through the bearing 11 of the front wheel frame 12. This spindle above the bearing is provided with a collar- 13 held in any adjusted zposition by a set screw 14 where by the front end of the frame may be raised or lowered to adjust the cultivators to the desired depth.

' The rear end I 1 and 2' is provided with a downturned extension 15 to which is secured a sleeve 16 in which issecured the spindle '18 for the bear ing 19 of the rearjwheelQ This bearing is of each of the side members held'in its adjusted position on the spindle by means ofan adjustable collar 20 vsimila rrto. the collar for the front Wheels, I

whereby the heightflof, :the frame relative to the groundmay be adjusted. The bearing 19 carries'a wheel prong'21 similar to the wheel ;prong 12 and it will be noted that V v each .of 'thezwheel prongs is inclined rear wardly so that a 'caster action will be given to the wheels and thefcultivator will tend to run in a straight line. Suitable ,cul-

tivator prongs .22 having cultivator shovels 23 ath-their lQWQDZGIIflSflLIG secured to the respective; longitudinally extending portions of the side frames so that the shovels will be arranged one behind the other but "in I track. n n

Near the rear end of the two side members I provide a cross brace 24 which comprises a pair of telescoped members 25 and 26, one having slots 27 to receive the bolts 28 of the staggered relation so that they will not otheru These two;members,*at their outer end, are curved as at-29 and secured to the sidemembers by bolts 30. By making the" cross brace adjustable, provision is made for the adjustment'of the two side members I relatively to one another to increase or decrease the width of the path cultivated.

Preferably on the cross member 24 I pro-' vide a spring support 31 for a drivers seat 32 and at the forward end the draft eye 33 is secured to the flange 7 of the support 6 whereby the'usual single tree 34 may be attached to the implement. v

In order that the down corn may be laid aside into'th'e two rows between which the cultivator is operatingand in order to also move to one side pumpkin vines and the like, I provide a shield 35 which is substantially U shaped and extends at its front end from the frame to within a comparatively short distance of the ground. I This shield at its front end is secured to the arcuate flange 7 preferably by the samebolts which hold the frame at its forward end, being slotted coincidently with the arcuate flange 7; The rear ends of the shield are secured to the respective down-turned portions 15 of the side members and this shield or corn turner is preferably formed of sheet metal such as heavy galvanized sheet iron or the like, which is sufliciently resilient to permit the side Wings to move with the rear ends of the side members when they are adjusted.

It will be seen that from the above construction IlliLVQ provided a riding cultivator, the shovels of which may be adjusted to operate at any desired depth in the ground and which is practically self-guiding. Due to the U shaped shield the down corn will be turned aside from out of the path of the cultivator and at the same time the roundedicorners of the shield'will come in contact with the standing corn of the rows on each side of the cultivator, in event 7 the cultivator tends to diverge from a straight line, and cause the cultivator to be moved back into its proper path between the rows of corn. Furtliiermore, due to the caster arrangement of the wheels, the

Wheels will tend to cause the cultivator to' travel in practically a straight line'and even whenturne'd to one side. or the other for any cause, tend to cause the cultivator to straighten, out. a c V I It is obvious that any form of Cultivators may bemounted on the frame and that instead of supporting shovel cultivators of transversely extending spacer bar connected to the rear end of each of said frame members, means for varying the length of said bar to vary the space between the rear ends of the frame members, a vertical spindle secured to the front ends of the frame members, and a vertical spindle secured to each by said frame, a riding seat mounted on said spacer bar, and a U shaped shield having adjustment of the frame, cultivators carried i its legs extending rearwardly surrounding:

said frame and extending downwardly to substantially enclose the frame and the cultivators, the legs of the shield being laterally adjustable with the rear ends of the side members. I

'In witness whereof, I, JOHN J. FRAZIER, have hereunto set my hand at Indianapolis,

Indiana.
